java.lang.String alGetString(int parameter)
int alGenSources()
int alGetError()
Each detectable error is assigned a numeric code. When an error is detected by AL, a flag is set and the error code is recorded. Further errors, if they occur, do not affect this recorded code. When alGetError is called, the code is returned and the flag is cleared, so that a further error will again record its code. If a call to alGetError returns AL_NO_ERROR then there has been no detectable error since the last call to alGetError (or since the AL was initialized).
Error codes can be mapped to strings. The alGetString function returns a pointer to a constant (literal) string that is identical to the identifier used for the enumeration value, as defined in the specification.

alSourceStop applied to an AL_INITIAL source is a legal NOP. alSourceStop applied to a AL_PLAYING source will change its state to AL_STOPPED. The source is exempt from processing, its current state is preserved. alSourceStop applied to a AL_PAUSED source will change its state to AL_STOPPED, with the same consequences as on a AL_PLAYING source. alSourceStop applied to a AL_STOPPED source is a legal NOP.

The data specified is copied to an internal software, or if possible, hardware buffer. The implementation is free to apply decompression, conversion, resampling, and filtering as needed.
8-bit data is expressed as an unsigned value over the range 0 to 255, 128 being an audio output level of zero.
16-bit data is expressed as a signed value over the range -32768 to 32767, 0 being an audio output level of zero. Byte order for 16-bit values is determined by the native format of the CPU.
Stereo data is expressed in an interleaved format, left channel sample followed by the right channel sample.
Buffers containing audio data with more than one channel will be played without 3D spatialization features – these formats are normally used for background music.

data
- the sample data.frequency
- the data frequency.void alSourcePlay(int source)
alSourcePlay applied to an AL_INITIAL source will promote the source to AL_PLAYING, thus the data found in the buffer will be fed into the processing, starting at the beginning. alSourcePlay applied to a AL_PLAYING source will restart the source from the beginning. It will not affect the configuration, and will leave the source in AL_PLAYING state, but reset the sampling offset to the beginning. alSourcePlay applied to a AL_PAUSED source will resume processing using the source state as preserved at the alSourcePause operation. alSourcePlay applied to a AL_STOPPED source will propagate it to AL_INITIAL then to AL_PLAYING immediately.
source
- the source to play.void alSourcePause(int source)
alSourcePause applied to an AL_INITIAL source is a legal NOP. alSourcePause applied to a AL_PLAYING source will change its state to AL_PAUSED. The source is exempt from processing, its current state is preserved. alSourcePause applied to a AL_PAUSED source is a legal NOP. alSourcePause applied to a AL_STOPPED source is a legal NOP.

void alSourceUnqueueBuffers(int source, int numBuffers, java.nio.IntBuffer buffers)
Once a queue entry for a buffer has been appended to a queue and is pending processing, it should not be changed. Removal of a given queue entry is not possible unless either the source is stopped (in which case then entire queue is considered processed), or if the queue entry has already been processed (AL_PLAYING or AL_PAUSED source). A playing source will enter the AL_STOPPED state if it completes playback of the last buffer in its queue (the same behavior as when a single buffer has been attached to a source and has finished playback).
source
- the target sourcenumBuffers
- the names count.buffers
- the buffer namesvoid alSourceQueueBuffers(int source, int numBuffers, java.nio.IntBuffer buffers)
The buffers will be queued in the sequence in which they appear in the array. This command is legal on a source in any playback state (to allow for
streaming, queuing has to be possible on a AL_PLAYING source). All buffers in a queue must have the same format and attributes, with the exception of
the NULL
buffer (i.e., 0) which can always be queued.
